（100+1）x（100除以2）=5050

1-2+3+4+5-6=5

84217432÷846368=88

答案是负的1007

你心里随便想一个数字,然后加上52.8再乘5,然后再减去3.9343,再除0.5后减去你心中想的那位数的十倍等于520.1314
其它很简单,换算一下,最后结果永远是（260.0657除以0.5）既为（520.1314）,中学水平,它是先设定一个数（520.1314）,再往上推.
如心中想一个数为X
得到如下程式：
（（〔X＋52.8〕×5）—3.9343）/0.5－10X
＝（5X＋264－3.9343）/0.5-10X
＝（5X＋260.0657）/0.5－10X
＝10X＋520.1314－10X
＝520.1314
所以无论用什么数,数是无关的,前后已冲掉,结果都一样的.你可以随便设定一个数,反推一条公式.
如：13709394等.

1/2+1/2+1/4+1/8+1/16+1/32+1/64
=1/2+1/2+1/4+1/8+1/16+1/32+1/64
=1/2+1/2+1/4+1/8+1/16+1/32+1/64+1/64-1/64
=1/2+1/2+1/4+1/8+1/16+1/32+1/32-1/64
=1/2+1/2+1/4+1/8+1/16+1/16-1/64
=1/2+1/2+1/4+1/8+1/8-1/64
=1/2+1/2+1/4+1/4-1/64
=1/2+1/2+1/2-1/64
=3/2-1/64
=127/64

这个题是这样的算的.设三个点的坐标,然后利用题目知F 为ABC的重心,接着利用重心坐标公式三个向量的横坐标之和为0可以推出三个点的横坐标之和为3这样,三个长度之和利用焦半径公式为X1+X2+X3+3p/2=6.(这是最简单的做法!）希望采纳!

找两个能算出整十的数加,在报纸上用线标上!比如波浪形,单下划线,双下划线!

由题意：
a+b=0
cd=1
x=5或者-5

当x=5时,
原式
=25-（0+1）×5+0的2005次方+（-1）的2006次方
=25-5+0+1
=21

当x=5时,
原式
=25-（0+1）×（-5）+0的2005次方+（-1）的2006次方
=25+5+0+1
=31

难忘的一件事
在我五岁那年的春节,有一件事使我难以忘怀,想知道吗?让我慢慢的记述给你听吧!
每当到了一年一度的春节,都会有很多亲戚朋友都会来我假拜年.有一次,爸爸的同事来我家拜年,爸爸妈妈准备了丰盛的菜,有时候菜不够,就去买一些下酒的熟菜.我看着爸爸和叔叔们喝着酒,一边不住的喊：“好酒!”我想菜是里面最好吃的了,听到爸爸和叔叔一 直说酒很好喝.我想酒的味道比菜的还要好吧!于是,我请求他们给我点酒喝,爸爸说：“小孩子家瞎胡闹什么?去,去,一边玩去.
”
机会来了,爸爸妈妈有事都出去了,就剩我一个人.哈,太好了,我走进厨房,在橱柜上有一瓶“五粮液”.我费了九牛二虎之力把那瓶梦寐以求的“酒”给搬下来了,放到了桌上,我迫不及待的喝了一口.叫了起来,真辣!辣到我头昏脑涨、天旋地转的坐在地上哭了起来.妈妈刚刚好回来了,看到我满面通红便问：“峥峥,怎么了?”我顿时说不出话来.妈妈又说：“是不是喝酒了.”我点点头,妈妈笑弯了腰,妈妈就带我进房里睡了一觉.起来时,出来就看了爸爸、妈吗、叔叔都笑了,我低下头走回房间不敢出来,你觉得我”傻“吗?

15%的浓度按照我做的经验,简单的搅拌设备就不行了,我们用的是德国的剪切机,剪切线速度可以达到20米/S,每分钟1万转,这样我嫌速度不够,只能分散到100纳米左右.如果能够达到30米/S以上估计可以做到几十纳米.
中文论文中讲述的分散剂我基本都试过,没有一个可以用来分散较高浓度二氧化钛的,如果浓度低到1%左右,只要有强力搅拌设备,有没有分散剂都不重要了,分散剂只是降低搅拌条件而已.
你想做高浓度的,必须购买高速搅拌设备,小试可以买国产设备,国产的做的也很不错,然后量大买德国产的设备.当然,也可以直接去德固赛买他们的分散液,40%浓度,你可以随意稀释,分散性都很好.

Guangzhou City is the capital of Guangdong Province.It’s the third largest city in China.Guangzhou has other beautiful nicknames such as " Flower city" and " The Goat City".Guangzhou is also a travel city with many tourist places,some of which are Zhenhai Tower,Liurong Temple,Flower Tower and the Pearl River.
The Baiyun Shan (White Cloud Mountain) is a great place to relax and enjoy a day among lush,rolling hills.It also offers great views over the city.The road to the top is restricted to park trams and pedestrians.To get to the top lookout point,you can use the main roads or trails.There are many places to rest and refreshments are available along the way.It is a great place to see people enjoying nature and playing games,such as badminton,football and even bungie jumping.
Besides,Guangzhou is famous for food,you can get delicious snacks in every corners.And "Dim sum" is the most favourite food for foreigners,they all enjoy it.

加加超市：3乘以0.9等于2.7 就相当于一个杯子2.7元.买180个 就是486元钱.
红红超市：买160个杯子 就是480元.160个杯子相当于买20套8个杯子.每8个杯子送一个就再加20个.共480元钱.
所以说红红超市便宜些.

脲醛胶是热塑性物质 固化剂为酸性 在酸性条件下反应固化,当然也可以不加 采用高温热压也可达到固化效果

一般都能找到一条可以直接计算的基本反应式,然后把其他式子看看,把基本反应式里涉及的产物与反应物分别挪到两边（就是把其他式子两头调换一下）
再配平一下,把基本式里没有的东西加减抵消掉
最后的反应热就是那几条式子乘上系数之后的代数和
最后,把式子掉过来的时候反应热记得变号

2a²+a+1>3a²-4a+1

为防止氯化铜的水解,在配制其溶液时,往往把氯化铜溶解在少量稀盐酸中.

X/A +Y/B + D/C=1,A/X+B/Y+C/Z =0,求X/A + Y/B + Z/C 的值?
(BCX+ACY+ABD)/ABC=1 ====> BCX+ACY+ABD=ABC ==> BCX+ACY=ABC-ABD
(YZA+XZB+XYC)/XYZ=0 ========>YZA+XZB+XYC=0
X/A + Y/B + Z/C= (XBC+YAC+ZAB)/ABC
=(XBC+YAC+ZAB)/(BCX+ACY+ABD)
=（ABC-ABD+ZAB）/（ABC-ABD+ABD）
=AB（C-D+Z）/ABC
=C-D+Z

最小的非负数是0
1-2-3+4=0
其他的符号也是这么填写
+ - - +
+2005-2006-2007+2008=0
最终结果是1002个0相加是0

符合
不必
键能是一定的
结果理论值,即使确实无法反应,但是结果也是正确的

这个很容易呀
令
f(x)=x-arctanx
f'(x)=1-1/(1+x^2)>0 (x>0)
所以函数单增,
f(0)=0
因此x>0时,f(x)=x-arctanx＞0
即x＞arctanx

这个只能用数学归纳法 首先N等于1,2时不成立只有N大于等于3成立.
先写一分之一加二分之一加三分之一一直加加到2的K次方分之一小于K,
在写一分之一加二分之一加三分之一一直加加到2的K+1次方分之一,前半部分到2的K次方分之一小于K,后面的项放缩小于 2的K+1次方分之2的K次方 小于1,所以原式得证.

设路程是X千米
10+(X-4)*2=28

10-9)(8-7)(6-5)(4-3)*2*1=2
(10-9)(8-7)(6-5)+4-3+2+1=4
(10-9)(8-7)(6-5)+4*3/2/1=6
10-9)(8-7)(6-5)+4+3+2-1=8
10-9)(8-7)(6-5)+4+3+2+1=10
给我分哈

这是操作符优先级问题,你可以查一下-=和++的优先级.
++比-=高,因此先算++,再算-=
不过c++的表达式结果是c,不是c+1,所以其实本题先算谁不影响结果.
